Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to novel sheet-shaped metal oxide microparticles, and to a transparent conductive film and a dispersion that have high transparency and conductivity, and excel in storage stability.

[0003] 2. Description of the Related Art

[0004] As a transparent conductive film, antimony- or fluorine-doped tin oxide films, tin- or zinc-doped indium oxide films, aluminum- or gallium-doped zinc oxide films, and the like have been known. The transparent conductive films are applied to, for example, transparent electrodes in liquid crystal display elements, plasma emission elements, electronic papers, etc., transparent electrodes for solar cells, heat-reflecting films, antistatic films, transparent heating elements, touch panels, electromagnetic wave shielding films, and the like.

[0005] In general, the transparent conductive film is produced by vapor deposition methods such as sputtering method, chemical vapor depo...
